What I'm looking for

I seek entry-level full-stack or front-end roles on collaborative teams where I can build intuitive UIs, work on impactful products, grow technical skills, and receive mentorship.

I am a Computer Science student at Kennesaw State University with a minor in Software Engineering, graduating December 2025. I build full-stack web applications and design intuitive user interfaces with a focus on reliability and usability.

During a systems-engineer co-op at Rovisys, I developed ladder logic for industrial automation, redesigned HMI screens, integrated JavaScript into HMIs, and performed hardware troubleshooting and network configuration to improve system performance and maintainability.

As a front-end software engineering intern at Generalized Robotics, I created responsive web and desktop UIs and integrated database access to streamline workflows. My projects include Study Buddy AI using OpenAI APIs and PDF parsing, a Java MVC Calculator tested with Playwright, and a music mood recommender built with React, Tailwind, Node.js, and Spotify OAuth.

I bring practical experience across front-end, back-end, and automation systems, strong testing and documentation practices, and a collaborative, learning-driven approach to engineering challenges.
